Thanks for the help. In looking at alsamixer I presume the
6 hypens across the top of various channels indicate the
possibility of recording, or "capture". The main PCM output
does not have these 6 hyphens so I presume it's not possible
to kick it into capture mode. The other two possibilities are
"Wave" and "Capture" but neither of them seem to do anything.
Regardless of whether I set "Mic" to mute or zero volume, all
I get when trying the two above mentioned options is noise
from the "Mic" device, even though turned down/off. I'm using
this procedure in seperate shells...
(diddle with alsamixer, hit escape)
pmidi -p 65:0 ~/MusE/Banana.mid (in one shell)
arecord -f cd -t wav -D copy foobar.wav (in other shell)
aplay --buffer-time=50000 -f cd -t wav foobar.wav
but I only ever get noise from the "Mic" input.
My .asoundrc includes...
pcm.copy {
type plug
slave {
pcm hw
}
route_policy copy
}
. any more clues for how to record PCM output ?
. how can I completely disable "Mic" recording ?
--markc
